“From day 1 of Austin & Ally, I wanted to write on our show,” Calum dished to JJJ. “We have the best writers in the business and I really look up to them. I basically just begged! [Creators] Kevin and Heath and the other writers were very supportive and walked me through the process.”

He continued, “In Season 2 I spent a lot of time in the writers room just watching them do their thing. A month before Season 3 Kevin and Heath called and told me Disney agreed to give me an episode! I was so grateful!”

“In this episode I am dressed as a Zalien in every scene! As the writer you go into note sessions with executives and producers, and every time we had a note session I had to do it in this GIANT Zalien costume!” Calum added about his get up for the episode.

In “Eggs & Extraterrestrials”, when Dez (Worthy), Trish (Raini Rodriguez) and Austin (Ross Lynch) convince Ally (Laura Marano) to attend the annual Zaliens Convention that’s being held in Miami, Trish and Dez happen to stumble upon real Zaliens and the foursome must devise a plan to survive.
